发明名称 Marine anchor
摘要 An improved marine anchor is disclosed for anchoring a marine vessel with an anchor rode. The anchor comprises a first and a second fluke connected to an anchor stock. An anchor shank has a pivot aperture disposed between a head portion and a tail portion of the anchor shank. The tail portion of the anchor shank may be provided with either an aperture or a slip ring for connecting to the anchor rode. The pivot aperture pivots the anchor shank on the anchor stock in a space between the first and second flukes. The improvement comprises a novel anchor crown secured to the anchor stock to limit the pivotal movement of the anchor shank upon contact of the head portion of the anchor shank with the anchor crown.
